Multifunctional energy-saving combustion system

Abstract

The invention discloses a multifunctional energy-saving combustion system. The multifunctional energy-saving combustion system comprises a furnace body, an injector burner, a heat exchanger and a fuel vaporization device. The injector burner is installed on one side of the furnace body and connected with the furnace body. The injector burner communicates with an inner cavity of the furnace body. A smoke exhausting pipe is arranged on the furnace body. The smoke exhausting pipe is connected with the heat exchanger. The fuel vaporization device is connected with a suction inlet of the injector burner through a conveying pipe. A combustion-supporting duct is arranged and connected with an air inlet of the injector burner through the heat exchanger. The combustion-supporting duct is provided with a branch pipeline and is connected with the fuel vaporization device. The multifunctional energy-saving combustion system has the beneficial effects that sufficient combustion is achieved to release the highest heat value, high temperature and low oxygen combustion can be achieved, nitrogen oxide emission is effectively reduced, the combustion efficiency is increased, full combustion is achieved under the high temperature and a low oxygen state, and emission of over 50% of nitrogen oxide can be reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of thermal energy, in particular to a multifunctional energy-saving combustion system that improves combustion efficiency and effectively reduces nitrogen oxide emissions. 【Background technique】 [0002] Nitrogen oxides include compounds such as nitrous oxide (N 2 O), nitric oxide (NO), nitrogen dioxide (NO 2 ), nitrogen trioxide (N 2 o 3 ), dinitrogen tetroxide (N 2 o 4 ) and dinitrogen pentoxide (N 2 o 5 )Wait. Except for nitrogen dioxide, other nitrogen oxides are extremely unstable, and turn into nitrogen dioxide and nitric oxide when exposed to light, humidity or heat, and nitrogen monoxide turns into nitrogen dioxide. Nitrogen oxides are toxic to varying degrees. [0003] Most of the NOx emitted by human activities comes from the combustion process of fossil fuels, such as the combustion process of automobiles, aircraft, internal combustion engines and industrial furnaces; it also comes from...

Problems solved by technology

But no matter which method, there is a large investment, and the flue gas flow rate is 15,000 m 3 The investment in small-scale treatment equipment per hour is not less than 3 million yuan; it has the characteristics of large area and high operating cost

It has greatly affected the enthusiasm of corporate governance and the continuity of operation

[0008] In addition, existing boilers still have relatively low combustion temperature, short combustion time, difficulty in burning fuel completely, low combustion efficiency and high nitrogen oxide content in flue gas, causing serious pollution to the environment
